Homes and walls in Surbiton
Surveys in Surbiton also cover the surrounding KT5 district and towns such as New Malden and Esher. London's housing includes a large stock of Victorian and Edwardian solid-wall terraces, inter-war semis and post-war blocks, and conservation areas cover many streets — so planning is often the first question for external work.
Much of Greater London sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
For blocks in Surbiton, we start with height, storeys and the planning position, because those decide the system.

Planning and building control in England
Planning in Surbiton follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
On residential buildings with a storey 11 metres or more above ground, guidance points to non-combustible external wall materials, and combustible materials are banned in relevant buildings 18 metres and over, so we specify mineral wool systems there.
Who needs to agree to EWI on a block?
The freeholder or management company commissions the work, but leaseholders usually pay through the service charge. In England and Wales, major works above the statutory threshold trigger the Section 20 consultation process before a contract is placed. We provide the specification and pricing you need for that consultation.

Flats and blocks in Surbiton: questions
Do flats need planning permission for EWI?
Yes. Permitted development rights for external alterations apply to houses, not flats or maisonettes, so an application is needed.
Who pays for EWI on a leasehold block?
In England and Wales, usually the leaseholders through the service charge, depending on the lease, and the landlord must follow the Section 20 consultation process for major works.
Can one flat have external wall insulation on its own?
Rarely. The outside walls are usually owned by the freeholder, the result would look patchy, and planning is unlikely. Whole-building schemes are the norm.
Do you cover Surbiton?
Yes — we survey and quote EWI for flats and blocks in Surbiton (KT5) and nearby New Malden, Esher and Morden, with a fixed written price before any work starts.
